The invention also relates to processes for and intermediates in the preparation of these compounds and to the use thereof in the control of harmful fungi.

2-Pyridylaminopyrimidine derivatives with a fungicidal effect are generally known from EP-A 407 899. They are suitable as plant protection agents against harmful fungi.

However, in many cases, their action is unsatisfactory. It is therefore an object of the present invention to find compounds with improved activity.

The phenylpyrimidine derivatives I defined at the start were accordingly found. Processes for and intermediates in their preparation, preparations comprising them for the control of harmful fungi and the use thereof for this purpose were also found.

The compounds of the formula I have, in comparison with the known compounds, an increased effectiveness against harmful fungi.

The compounds I are distinguished from the known compounds through the substitution of the 5-phenyl ring, in which at least one ortho-substituent is not hydrogen.

Compounds of formula I are accessible, for example, according to the following synthetic route,

in which, in formula III, R is C₁-C₆-alkyl. The reaction usually takes place in a protic solvent, such as, e.g., alcohols, especially ethanol. However, it can also be carried out in aprotic solvents, such as, e.g., pyridine, N,N-dimethylformamide, N,N-dimethylacetamide, or mixtures thereof. The reaction is usually carried out at 50 to 250° C., preferably at 100 to 200° C. [cf.: Austr. J. Chem., Vol. 32, pp. 669-679 (1979); J. Org. Chem., Vol. 58, pp. 3785-3786 (1993); Arm. Xim. ZH, Vol. 38, N11, 718-719 (1985)].

As a rule, it is advantageous to operate in the presence of a base, which can be used in equimolar amounts or also in excess. Alkali metal and alkaline earth metal alkoxides, such as sodium methoxide, sodium ethoxide, potassium ethoxide or potassium tert-butoxide, especially sodium ethoxide, or also nitrogenous bases, such as triethylamine, triisopropylethylamine and N-methylpiperidine, especially pyridine and tributylamine, are possible as bases.

The components are usually used in approximately stoichiometric amounts. However, it can also be advantageous to use one of the components in excess.

The starting materials of the formulae II and III are known in the literature [cf. EP-A 588 146; EP-A 1 002 788; WO-A 98/41496], some are also commercially available or can be prepared according to the cited literature.

Compounds IV are converted to the dichloropyrimidines of the formula V [cf. U.S. Pat. No. 4,963,678; EP-A 745 593; DE-A 196 42 533; WO-A 99/32458; J. Org. Chem., Vol. 58, pp. 3785-3786 (1993); Helv. Chim. Acta, Vol. 64, pp. 113-152 (1981)].

POCl₃, PCl₃/Cl₂ or PCl₅, or mixtures of these reagents, for example, are suitable as chlorinating agent [Cl]. The reaction can be carried out in excess chlorinating agent (POCl₃) or an inert solvent, such as, for example, acetonitrile or 1,2-dichloroethane. It is preferable to carry out the reaction in POCl₃.

This reaction usually takes place between 10 and 180° C. For practical reasons, the reaction temperature usually corresponds to the boiling temperature of the chlorinating agent (POCl₃) or of the solvent used. The process is advantageously carried out with the addition of N,N-dimethylformamide, in catalytic or substoichiometric amounts, or of nitrogenous bases, such as, for example, N,N-dimethylaminiline.

The dichlorinated compounds of the formula V are converted to the compounds of the formula I, in which R² is chlorine, by amination with VI.

This reaction is usually carried out at 0 to 150° C., preferably at 20 to 120° C. [cf. J. Chem. Res. S (7), pp. 286-287 (1995), Liebigs Ann. Chem., pp. 1703-1705 (1995)] in an inert solvent, optionally in the presence of an auxiliary base.

Protic solvents, such as alcohols, for example, ethanol, or aprotic solvents, such as aromatic hydrocarbons or ethers, for example toluene, o-, m- and p-xylene, diethyl ether, diisopropyl ether, tert-butyl methyl ether, dioxane or tetrahydrofuran, in particular tert-butyl methyl ether or tetrahydrofuran, are possible as solvents. NaHCO₃, Na₂CO₃, Na₂HPO₄, Na₂B₄O₇, diethylaniline or ethyldiisopropylamine, for example, is suitable as auxiliary base.

The components are generally used in an approximately stoichiometric ratio. However, it can be advantageous to use the amine in excess.

The amines of the formula VI are commercially available or are known in the literature or can be prepared according to known methods.

Compounds of the formula I in which R² is alkoxy are obtained from the corresponding chlorinated compounds of the formula I in which R² is chlorine by reaction with alkali metal or alkaline earth metal alkoxides [cf.: Heterocycles, Vol. 32, pp. 1327-1340 (1991); J. Heterocycl. Chem., Vol. 19, pp. 1565-1567 (1982); Geterotsikl. Soedin, pp. 400-402 (1991)].

Compounds of the formula I in which R² is cyano are obtained from the corresponding chlorinated compounds of the formula I (R²=Cl) by reaction with alkali metal, alkaline earth metal or metal cyanides, such as NaCN, KCN or Zn(CN)₂ [cf.: Heterocycles, Vol. 39, pp. 345-356 (1994); Collect. Czech. Chem. Commun., Vol. 60, pp. 1386-1389 (1995); Acta Chim. Scand., Vol. 50, pp. 58-63 (1996)].

Compounds of the formula I in which R² is hydrogen are obtained from the corresponding chlorinated compounds of the formula I (R²=Cl) by catalytic hydrogenation [cf.: J. Fluorine Chem., Vol. 45, pp. 417-430 (1989); J. Heterocycl. Chem., Vol. 29, pp. 1369-1370 (1992)] or by reduction with zinc in acetic acid [cf.: Org. Prep. Proced. Int., Vol. 27, pp. 600-602 (1995); JP-A 09/165 379].

Compounds of the formula I in which R² is C₁-C₆-alkyl or C₁-C₆-haloalkyl (formula Ia) can be prepared, analogously to the synthetic sequence described for the compounds I in which R² is chlorine, by suitable modification of the starting materials of the formula III. Instead of the phenylmalonic esters of the formula III, phenyl-β-ketoesters of the formula VII in which R² represents alkyl or haloalkyl are used with the amidine of the formula II. The following reactions are carried out analogously to the syntheses described above for the compounds with R²=chlorine.

The compounds of the formulae IVa and Va are novel.

The reaction mixtures are worked up conventionally, e.g. by mixing with water, separating the phases and possibly chromatographic purification of the crude products. Some of the intermediates and final products are obtained in the form of colorless or slightly brownish viscous oils which, under reduced pressure and at moderately elevated temperature, are freed or purified from volatile constituents. Provided that the intermediates and final products are obtained as solids, the purification can also take place by recrystallization or trituration.

If individual compounds I are not accessible by the routes described above, they can be prepared by derivatization of other compounds I.

Example 1 6-Chloro-5-(2,4,6-trifluorophenyl)-4-isopropylamino-2-(2-pyridyl)pyrimidine [I-1] a) 4,6-Dihydroxy-5-(2,4,6-trifluorophenyl)-2-(2-pyridyl)pyrimidine

332 g (1.16 mol) of diethyl 2-(2,4,6-trifluorophenyl)malonate and 192 g (1.04 mol) of tributylamine were heated at 180° C. for eight hours together with 182 g (1.17 mol) of pyridine-2-carboxamidine. In the course of this, the ethanol produced was distilled off. The reaction mixture was then allowed to cool to 60-70° C. and was mixed with a solution of 116 g (2.89 mol) of sodium hydroxide in 1200 ml of water. After stirring for 30 min and cooling to approximately 20-25° C., the mixture was extracted with methyl tert-butyl ether (MTBE) and, after phase separation, the aqueous phase was acidified with 6N hydrochloric acid. After filtering off and drying, 180 g of the title compound were obtained.

¹H NMR: δ (ppm, d₆-DMSO)=8.75 (d); 8.3 (d); 8.1 (t); 7.6 (m); 7.1 (t).

b) 4,6-Dichloro-5-(2,4,6-trifluorophenyl)-2-(2-pyridyl)pyrimidine

A suspension of 80.4 g (0.252 mol) of the pyrimidine from ex. 1a in 515 g (3.36 mol) of phosphorus oxychloride was heated at 120° C. for 8 hours and then concentrated under vacuum. The residue was taken up in dichloromethane and water. After phase separation, the organic phase was dried and freed from the solvent. After chromatography on silica gel (cyclohexane/ethyl acetate), 26 g of the title compound were obtained.

¹H NMR: δ (ppm, CDCl₃)=8.9 (d); 8.6 (d); 7.8 (t); 7.5 (m); 6.8 (t).

c) 6-Chloro-5-(2,4,6-trifluorophenyl)-4-isopropylamino-2-(2-pyridyl)-pyrimidine

A solution of 3.30 g (0.093 mol) of the dichloride from ex. 1b in 4.5 ml of dimethylformamide (DMF) and 2.7 g (0.046 mol) of isopropylamine was stirred at 40° C. for 24 hours. After cooling to 20-25° C., the mixture was extracted with dichloromethane and the organic phase was washed with water and saturated NaHCO₃ solution, then dried and freed from the solvent. After chromatography on silica gel (cyclohexane/ethyl acetate), 3.05 g of the title compound were obtained.

The determination of the lipophilicity parameter log P_(ow) (Table I) was carried out in accordance with OECD test guidelines using the RP HPLC run time method.

To this end, a log k′/log P_(ow) correlation curve based on ten reference substances was plotted and was validated with the help of the lipophilicity parameters of eight comparison substances established through the extraction method.

A commercially available reversed-phase C₁₈ stationary phase was used as stationary phase. Chromatographic separation was carried out with methanol and a buffer solution as mobile phase at pH 7.4 under isocratic conditions.

The retention times of the standards t_(R) were converted in accordance with equation Φ into the capacity factors k′, in which t₀, as reaction time of the solvent unretarded on the reversed-phase C₁₈ stationary phase, represents the dead time of the chromatographic system:

$k^{\prime} = {\frac{t_{R} - t_{0}}{t_{0}}\Phi}$

The linear correlation of the log k′ values with the log P_(ow) values of the standards published in the appendix to the guidelines 92/69/EEC yields the correlation curve through linear regression.

The lipophilicity parameters log P_(ow) of the analytes were after calculation of the logarithmic capacity factor log k′ interpolated from the correlation curve of the standards.

The validation of the RP HPLC analytical method described and of the standards used is carried out with the help of eight comparison active compounds, the distribution behavior of which was determined with the help of the extraction method.

EXAMPLES FOR THE ACTION AGAINST HARMFUL FUNGI

The fungicidal action of the compounds of the general formula I can be demonstrated from the following tests:

The active compounds were prepared, separately or together, as a 10% emulsion in a mixture of 70% by weight of cyclohexanone, 20% by weight of Nekanil® LN (Lutensol® AP6, wetting agent with an emulsifying and dispersing action based on ethoxylated alkylphenols) and 10% by weight of Wettol® EM (nonionic emulsifier based on ethoxylated castor oil) and were appropriately diluted with water to the desired concentration.

Use Example 1 Activity Against Alternaria solani on Tomatoes

Leaves of pot plants of the variety “Groβe Fleischtomate St. Pierre” were sprayed to runoff point with an aqueous suspension prepared from a stock solution consisting of 10% of active compound, 63% of cyclohexanone and 27% of emulsifier. On the following day, the leaves were infected with an aqueous suspension of zoospores of Alternaria solani in 2% Biomalz solution with a concentration of 0.17×10⁶ spores/ml. The plants were subsequently placed in a chamber saturated with water vapor at temperatures between 20 and 22° C. After 5 days, early blight in the untreated but infected control plants had so extensively developed that the infection could be visually determined in %.

In this test, the plants treated with 63 ppm of the active compounds I-1 to I-7, I-9 to I-16, I-20, I-24, I-25, I-32 and I-33, I-51, I-54, I-58, I-59, I-62, I-63, I-64, I-66, I-67, I-68 and I-94 showed a maximum of 3% infection, while the untreated plants were 100% infected.

Use Example 2 Activity Against Botrytis cinerea on Capsicum Leaves

Capsicum seedlings of the variety “Neusiedler Ideal Elite” were, after 4 to 5 leaves had fully developed, sprayed to runoff point with an aqueous preparation of active compound prepared from a stock solution consisting of 10% of active compound, 85% of cyclohexanone and 5% of emulsifier. The next day, the treated plants were inoculated with a spore suspension of Botrytis cinerea comprising 1.7×10⁶ spores/ml in a 2% aqueous Biomalz solution. The test plants were subsequently placed in a controlled-environment chamber at 22 to 24° C. and high atmospheric humidity. After 5 days, the extent of fungal infection on the leaves could be determined visually in %.

In this test, the [lacuna] with 250 ppm of the active compounds I-1 to I-7, I-9 to I-14, I-20, I-24, I-32 to I-41 and I-43, I-51, I-53, I-55, I-56, I-57, I-58, I-59, I-62, I-63, I-64, I-66, I-67, I-68, I-82, I-83, I-86, I-87, I-88, I-90 and I-115 showed up to 5% infection, while the untreated plants were 90% infected.

Use Example 3 Protective Activity Against Powdery Mildew of Cucumber Caused by Sphaerotheca fuliginea

Leaves of pot-grown cucumber seedlings of the variety “Chinesische Schlange” in the cotyledon stage were sprayed to runoff point with an aqueous preparation of active compound prepared from a stock solution consisting of 10% of active compound, 85% of cyclohexanone and 5% of emulsifier. 20 hours after the spray coating had dried on, the plants were inoculated with an aqueous suspension of spores of powdery mildew of cucumber (Sphaerotheca fuliginea). The plants were subsequently cultivated for 7 days in a greenhouse at temperatures of between 20 and 24° C. and a relative atmospheric humidity of 60 to 80%. The extent of mildew development was then determined visually in % of infection of the cotyledon area.

In this test, the [lacuna] with 63 ppm of the active compounds I-1, I-3, I-5 to I-10, I-12, I-13, I-16, I-18, I-21, I-32, I-33, I-51, I-52, I-54, I-55, I-56, I-58, I-59, I-62, I-63, I-64, I-66, I-67, I-68 and I-83 showed a maximum of 10% infection, while the untreated plants were 100% infected.

Use Example 4 Activity Against Net Blotch of Barley

Leaves of pot-grown barley seedlings of the variety “Igri” were sprayed to runoff point with an aqueous preparation of active compound prepared from a stock solution consisting of 10% of active compound, 63% of cyclohexanone and 27% of emulsifier. 24 hours after the spray coating had dried on, the leaves were inoculated with an aqueous suspension of spores of Pyrenophora [syn. Drechslera] teres, the causative agent of net blotch. The test plants were subsequently placed in a greenhouse at temperatures of between 20 and 24° C. and a relative atmospheric humidity of 95 to 100%. After 6 days, the extent of development of the disease was determined visually in % of infection of the total leaf area.

In this test, the plants treated with 63 ppm of the active compounds I-1 to I-6, I-10, I-12 to I-14, I-32, I-33, I-38, I-43, I-51, I-56, I-64 and I-86 showed not more than 15% infection, while the untreated plants were 90% infected.
